Frequency Input 2-Wire Transmitters Precision, Isolated, Rangeable Model 20/7, (L) F E AT U R E S : • 2-wire transmitter system • Eliminates ground loop errors • User selectable ranges • Over 1000 Volts Isolation • Wide ranging ZERO and SPAN • DIN rail mounting AVAILABLE OPTIONS: • 3-1/2 digit backlit LCD indicator • Input sensor linearization The model 20/7 is a precision, loop powered 2-wire • Input voltage to 750 Volts transmitter with galvanic isolation between its input and • Higher I/O isolation the current-loop output signal. The 20/7 provides the necessary circuitry for amplification and processing of • NEMA 4X or NEMA 7 enclosure F requency/Pulse signals from various sensors such as flowmeters, cams, encoders, tachogenerators and many other types of rotating machinery. The output is a 4-20mA output signal which is linearly proportional to the input frequency or pulse rate. An optional LCD indicator is available on the 20/7 to indicate the output in Engineering Units. The 20/7 can be easily ranged without requiring special tools or board modifications. The model 20/7L also provides signal linearization to correct for the inherent non-linearity of sensors such as turbine/paddle flowmeters. ATEST terminal provides a 40-200mV signal proportional to the 4-20mA output. Applying a DVM to the TEST terminals allows monitoring and verification of output without interrupting or disconnecting the current loop.
